I would be interested in buying a pickup if it's the original sb1000 passive humbucker
Russ, I have this left-handed 1979 SB-1000 which is somewhere in 1980 "pimped-up" with two more original MB-Ie pickups, so I nicknamed it "SB-3000".
All pickups are original and fully working.
As currently I have few Arias SB on restoration, I am not sure what to do with this "SB-3000", and one option is to restore it and sell or to use it for parts and sell that way (maybe to sell as-is - it is working, just electronics is a bit rewired to accomodate 3 pickup, but all parts inside are original).
Anyway, if you`re interested to buy just a pickup, make me an offer (here or PM), so I`ll think about it.
